Company

The EUY US trademark and the EUYBIKE application are recorded to an individual owner in Shenzhen, China.
The brand's e-bikes are also listed on Amazon under the EUYBIKE name.

Where it sells

Euy e-bikes are sold in the US through the brand's own store at euybike.com, which ships free to the lower 48 from warehouses in Walnut and Rialto, California.
The store's terms name the operator only as "euy", and its privacy policy is an unfilled template, so the store names no legal entity.
Its store sells fat tire, folding, moped-style and utility e-bikes on 20-inch wheels.

Description

The Euy F8 is a step-through fat tire cruiser with a removable 48 V, 20 Ah battery of 960 Wh (48 V x 20 Ah) and a 750 W rated geared rear hub motor with 72 Nm of torque (1,000 W peak).

It has mechanical disc brakes with 180 mm rotors, a lockable 80 mm front suspension fork, a suspension seatpost and 20 x 4.0 in fat tires. It weighs 78 lb with the battery and 70.2 lb without, and is rated for a 400 lb maximum load. A padded rear passenger seat with a backrest sits on the rear rack.

The maker claims 28 mph, 45 to 50 miles on throttle and 74 to 80 miles with pedal assist. It has a half-twist throttle, five assist levels, a colour LCD, a 48 V LED headlight, an automatic brake light, plastic fenders, a Shimano 7-speed drivetrain and an IPX5 rating.

Green, Black and Pink sell at one price, and White is sold out. A spare F8 battery is listed at $299.00.
